Application filed January 25, 1911. Serial No. 604,564.

7 To all whom it may concern:

Be it known thatl, Hanan B. Bown, a citizen of the United States,residing at Wilmington, in the-county of Newcastle and State ofDelaware, have invented certain new and useful Improvements" in Smoke- 1"Qonsumers, of which the following is a Specification, reference beinghad therein to the accompanying drawing.

This invention relates, in its broad idea,-. to a smoke consumer for useparticularly in locomotives; although it maybe employed with equaladvantage in the fire boxes of air mixing with the gases stationary ormarine boilers. I

It is a well knowniiact that smoke is caused by poor cpr'nbustion andinsufiicient from the burning fuel.

While I- am aware that numerous devices have been employed with somesuccess for supplying a greater amount of air to the fire box than isintroduced therein by a natural draft; these devices, as a rule, havebeen faulty in that, being subjected to the intense heatof thefirebox,-they becorne burned out and useless within a short time;

face of the fire box.

' cheap, durable and efiicient; and easily in-' I vide a device and alsothey detract from the heating sur- My present invention to a novelconstruction and application of air jet pipes, or nozzles, and operatingmeans for introducing a supply of heated air into the firebox to mixwith the gases to produce a more perfect combustiomand thus consume thesmoke. I

The objects of'the invention are to provide an airpipe or nozzle, thatshall be stalled in the fire box of any boiler, either locomotive,marine or stationary.

Another object of the invention is to proof this class that shall beeasily operated, and that is so constructed that it will withstand theheat to which it is subjected With these and other objects in view, myinvent-ion consists in, certain construction and combination of parts aswill hereinafter be fully; described and claimed and illustrated in theaccompanying drawings, which form a part of this application, and inwhich like figures of reference refer to. corresponding parts in all ofthe views; but it is fully understood that while I have described myinvention as shown in the drawrelate's particularly ings, that I do notconfine myself to the exact design, as slight changes may be made in theconstruction and arrangement of the several parts without departing fromthe spirit of the invention, y

In the drawings :-Figure 1, is a front view of the device, showing thesame in stalled in the fire box of a locomotive. Fig.

is a top plan view of the same. Fig. 4-, is a detail "ertical sectionalview of the nozzle, and illustrates the method of securing the same tothe rear wall of the fire box.

Referring to the drawings, my device I comprises a'double walledairnozzle 1, of iron or steel, or other suitable material,-

which is formed with the curved discharge end 2, having an elongateddischarge opening 3, therein of the proper form to.properly distributethe air throughout the fire box. Said air nozzle 1, is also formed withthe hollow bosses 4:, extending at rightangles from the rear thereof;and the ducts 5, in said bosses communicating with the water chamber6,,tormed by the double walls of said nozzle 1. Said air nozzles 1,arepreferablyplaced in the two rear cor ners of the fire box 7, and areshown as'attached thereto in the following way although they may besecured in any suitable manner.. comprises the plates 8, and 9, whichare spaced apart and form the water leg'lO; while-at suitable places,said plates 8, and

andwithin said tubes 11, are inserted the 2, is a side elevation of thesame. Fig. 3,

bosses 4, of the air nozzle 1, which are held therein by the nut 12,threaded 'thereon a and by this method of mounting the air nozzle 1, noprovision has'to be made -for expansion andcontraction in" the Waterpipes, as they are all-without the fire box 7 I Said bosses 4, areprovided with the inter-- nalscrew-threads 13, b which are secured thewater pipes 14, whlch'havetheir other ends tapped into the outer late8;and in this manner, a circulationo water is main-" tained through thewater chamber or jacket 6, from the water he 10, ofthe boiler; saidwater pipes i l, being supplied with the' cut off valves 15, for thepurposeiof preventing the water entering the fire box, if one of the airbroken. There is alsoprovided a flushing valve 16, placed in the lowerpipe 14, be-

nozzle's 1,. should become tween the valve 15, and the nozzle 1, forIghe purpose of cleaning outsaid water cham- The lower end 17, of theair nozzle 1, is reduced in diameter below the lower end of the waterchamber 6, and extends downward through the grate 18, and is connectedby a T-fitting 19, to an air pipe 20; said air pipe 20, connectstogether both of the air nozzles 1, and has secured to each end, acurved intake air pipe 21, which extends from the side of thelocomotive, and is fitted with a netted intake funnel 22, on the endthereof, in such a manner, that while the locomotive is in motion,suflicient air will enter the intake funnels 22, to discharge from thenozzles 1, into the fire box; the air being heated as it passes throughthe nozzles 1, by the heat therefrom. To produce the same result andsupply the air .tor the nozzles, while the locomotive is standing still,an air pipe 23, is attached to the air pipe 20, running from the usualforce draft pipe from the power blower (not shown). Also for starting acirculation of air through the nozzle 1, a steam jet pipe 24, isattached to the T-fittings 19; the admission of steam being controlledby a valve 25.

Having thus described my invention what I claim as new and desire tosecure by Letters Patent is In a smoke consumer of the class described,the combination with a fire box having a water-leg, and air inletand'supply pipes leading to said fire box, and an air discharge nozzlemounted in said fire box and connected to said air supply pipes, saidair discharge nozzle formed with a water jacket, of hollow bossesintegral with and extending from said air discharge nozzle through thewall of said fire box, and

means for connecting said hollow bosses to the water leg of said firebox.

In testimony whereof I affix my signature in presence of two Witnesses.
